Objective: Relate 3D shapes with the 2D figures

Subtopics to be covered:

- Define 2D plane figures, 3D solid shapes with examples

- Vertices, Edges, Faces for a 3D solid shape and the shape of faces

- Nets for the 3D solid shapes

Learning Outcome:

- Students can identify the 2D figure to a 3D solid shape

- They can tell the number of faces, vertices and edges for a solid shape

- They can draw a 2D net for a 3D solid shape
